[It was] David himself [who] said by [inspiration of] the Holy Spirit [Psa. 110:1], ‘The Lord [i.e., God] said to my [i.e., David’s] Lord [i.e., Jesus], sit at my right side until I make your enemies the footrest [i.e., in subjection] under your feet.’
Then Jesus said to the apostles, “These are the words that I told you while I was still with you, [when I said] that everything written in the Law of Moses, and the prophets, and the psalms about me needed to be fulfilled.”
[He said], “Brothers, it was necessary that the Scriptures be fulfilled which the Holy Spirit spoke through King David about Judas, who guided the soldiers who came to arrest Jesus.
And again, Isaiah says [ 11:10], “A root [i.e., a descendant] from Jesse will appear [i.e., Christ], and He will rise up to rule over the nations, and the Gentiles will place their hope in Him.”
God again identified a certain day, [calling it] “Today,” in David’s [writings], a long time later (just as it was referred to above) [Psa. 95:7-8], “Today, if you hear His [i.e., God’s] voice, do not have a stubborn heart.”
Since God wanted to show conclusively to those who would inherit the promise [i.e., Abraham and all of his spiritual descendants], how unchangeable His purpose was, He confirmed it with an oath.
(for [Levitical] priests were appointed without [God] taking [such] an oath, but Christ was appointed with an oath by God when He said to Him [Psa. 110:4], “The Lord made a vow and will not change His mind [when He said], ‘You are a priest forever’).”
These kings and the beast will wage war against the Lamb, and the Lamb will conquer them, for He is the Lord of lords and the King of kings. And those who are called and chosen [by God], and who are faithful [to Him will share the victory] with the Lamb.”
